Over-the-air update ITRM-26.BG.FG SuperDuty

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

SSM 552392026-10-13. Service bulletin. Some 2023-2026 F-Super Duty vehicles equipped with a trailer brake control module and built on or before 08-May-2026 may exhibit a "Trailer Disconnected" message after cycling the ignition off and back on with a trailer connected. This may be due to the presence of an integrated battery charger on a trailer equipped with electric over hydraulic brakes. If trailer functionality is restored after unplugging and plugging the trailer connector back in while the ignition is on, this condition can be corrected by downloading and performing the "Trailer Brake Configuration" application using the latest software version of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 19H332 and labor operations 12651D and 12651D4. Workshop Manual (WSM), Section 417-01 Exterior Lighting > Diagnosis and Testing > Trailer Lamps > Pinpoint Test G The Message Center Displays A False Trailer Disconnected Message When A Trailer Is Connected To The Vehicle - Only For Electric Over Hydraulic (EOH) Equipped Trailers When Vehicle Trailer Brake Type Setting Is Set To Electric Over Hydraulic has bee
SSM 552082026-09-30. Service bulletin. Some 2024-2026 F-150, 2025 Explorer/Aviator, 2025-2026 Expedition/Navigator, or 2026 F-Super Duty vehicles may exhibit diagnostic trouble code (DTC) U211B:43:48 stored in the body control module (BCM) when performing a Self-Test. This DTC sets due to an internal BCM timing issue during the self-test process. This specific code has no customer impact and does not cause any drivability concerns or warning messages. Clearing DTC U211B:43:48, reprogramming the BCM, or replacing the BCM is unlikely to prevent this DTC from setting. This DTC does not trigger a condition covered under warranty. Note: This guidance only applies to U211B with the specific failure byte 43 in status 48. Any other trusted real-time operation network (TRON) DTCs or different failure bytes associated with U211B are still applicable and technicians must follow Workshop Manual (WSM) normal diagnostics for those DTCs.

SSM 551162026-09-01. Service bulletin. Some of the following vehicles: * 2025-2026 Expedition/Navigator built on or after 02-Feb-2025 * 2025-2026 F-Super Duty built on or after 02-Feb-2025 * 2025-2026 Explorer/Aviator built on or after 02-Feb-2025 * 2025-2026 Nautilus built on or after 17-Feb-2025 * 2025-2026 F-150 built on or after 16-Jul-2025 may exhibit all of the following symptoms: - "No Key Detected" message displayed on the instrument panel cluster (IPC) - Key fob does not work in the backup slot. - Remote keyless entry (RKE) (lock and unlock from the key fob) functionality will work to lock/unlock the vehicle. If the vehicle exhibits these symptoms, manually enter the vehicle identification number (VIN) into the VIN entry dialog in the Ford Diagnosis and Repair System (FDRS) and then start a session using the Vehicle Communication Module (VCM) II, VCM 3, Vehicle Communication and Measurement Module (VCMM) or later level device with a universal serial bus (USB) cable disconnected from the laptop. Download the "BCM - Body Control Module (BCM) Hardware Test" app
SSM 550312026-07-28. Service bulletin. Some 2021-2026 Ford/Lincoln vehicles may exhibit various symptoms including but not limited to the auto start/stop system not operating as intended with a "Check Charging System" message in the instrument panel cluster (IPC) while the charging system is operating properly with no charging related diagnostic trouble codes (DTC) stored. This may be due to someone using an aftermarket programmer to change the body control module (BCM) configuration to disable the auto start/stop system or perform other unsupported programming modifications. To correct this condition on F-150 and Bronco vehicles, download and run the Ford Diagnosis and Repair System (FDRS) application titled "BCM-Charging System Configuration Correction". Running this application will determine if the BCM configuration was modified by the customer and if so, provide the option to return the configuration back to factory settings. For other vehicle models exhibiting concerns related to unsupported aftermarket BCM programming, submit a Technical Support Request (TSR) requesting support to revert the BCM configuration
SSM 550212026-07-21. Service bulletin. Some 2025-2026 Bronco/Bronco Sport/Corsair/F-150/F-Super Duty/Maverick/Mustang/Mustang Mach-E/Ranger vehicles may exhibit a no audio/sound condition. This may be due to the software in the audio control module (ACM). To determine if it is a software concern, disconnect the vehicle's 12-volt battery cables for 10 minutes and reconnect. If the concern is still present, continue with normal diagnostics in Workshop Manual (WSM), Section 415-00 Information and Entertainment System > General Information > Diagnosis and Testing and repair as necessary outside of this article. If the no audio/sound concern is resolved, reprogram the ACM using the latest software level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 18C869 and labor operations 10654C, 12651D and 12651D4.
SSM 549792026-07-08. Service bulletin. Some 2023-2025 Mustang Mach-E and 2024-2026 F-Super Duty vehicles equipped with a 360-degree camera may exhibit a distorted or corrupted 360-degree camera image in the center display screen, but the rear-view camera image is operating correctly. To restore the 360-degree camera image, download and run the "IPMA - Reset the Image Processing Module A (IPMA) Calibration Data" application using the Ford Diagnosis and Repair System (FDRS) scan tool. Then download and run the "IPMA - 360 Degree View Camera Alignment" application. Inform customers that they can continue to drive the vehicle and engineering is currently working on a software solution for this condition that is expected in Q3 of 2026. Replacement or reprogramming of the IPMA will not resolve this condition. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available. If a vehicle exhibits this condition, enter a vehicle identification number (VIN) and click the "Submit Global Concern Report (GCR)" link at the upper right of the PTS
SSM 549752026-07-07. Service bulletin. Some 2023-2026 F-Super Duty vehicles equipped with a 10R100 or 10R140 transmission may exhibit an intermittent failure to engage forward or reverse gears and/or a loud whining noise. Additionally, the driver will be able to shift back to park. This may be due to PCM software being unable to command the transmission solenoid clutch actuators when the battery has a low state of charge (SoC) and/or the vehicle has been jump started. To restore proper transmission functionality, charge the battery as stated in the Workshop Manual (WSM), Section 414-01 Charging System > General Information. Cycle the ignition on then off and leave the vehicle off for 5 minutes to confirm the condition is no longer present. To prevent this issue from reoccurring, refer to the Owner's Manual > Storing Your Vehicle > Preparing Your Vehicle for Storage > 12V Battery. Replacement of transmission components will not resolve this condition. Inform the customer that the condition has no impact on transmission durability. For claiming, use causal part 12A650 and labor operations 12650D, 12650D45, and 12650D81.
TSB 26-22972026-06-29. Service bulletin. Some of the vehicles listed in the model statement above equipped with SYNC4 may experience a blank center display screen or black center display after welcome animation. The rear-view camera will still function when shifting the vehicle to reverse under these conditions.
